Question

find; (a) (3x + 2)²
(b) (4x-3) ²​

Answer 1

Answer:

a.9x²+12x+4 b. 1x²-24x+9

Step-by-step explanation:

a. (3x+2)²= (3x)²+2*3x*2 + (2)²= 9x²+12x+4

b.(4x-3)²= (4x)²-2*4x*3+(3)²= 16x²-24x+9

Answer 2

We can find the answer by using this formulae

a² + 2 ab + b² and a² - 2ab + b²

a = 3x , b = 2

(3x)² + 2(3x)(2) + (2)²

9x² + 12 x + 4

B. a = 4x , b = 3

(4x)² - 2(4x)(3) + (3)²

16x² - 24x + 9

have a good day
